The stria? that have been described, differ in size from the finest scratch visible up to a 

 furroAv a foot deep. The largest single groove we have seen with the dimensions just 

 indicated, occurs in hard limestone in Whiting, a few miles south of Middlebury, on the 

 west side of the main road. This furrow is several feet long. But the most remarkable 

 grooves we have seen, when we consider their length, were observed on the Missisco River, 

 just after the river passes out of the Troy valley northward into Canada. On the west 

 .side of the river and of the road, within the limits of Potton, and at the northeast side 

 of Jay Peak, the talcose slate shows itself in ledges, rounded by a force directed southerly, 

 or up the stream, and there we found strise six inches wide, three inches deep, and three 

 or four rods long. The rock is very hard, and the force which could have ploughed out 

 such deep and straight furrows must have been enormous. Generally the scratches are 

 less than half an inch deep.
